WILLIAM J. SHERRIFF, OF ALLEGHENY, PENNSYLVANIAH,

INJECTOR.

SPECIFICATION forming part of Letters Patent No.337,877,dated March 16, 1885.

Application filed September 26, 1885. Serial No, 178,307.

To all whom it may concern.-

Be it known that I, \VILLIAM J. SHER- RIFF, of Allegheny city, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Injectors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form part of this specification, in which Figure l is a longitudinal sectional view of my improved injector. Fig. 2 is side elevation of the same. Fig. 3 is a front elevation of a modification.

In the drawings, a represents the shell, of suitable size and form of construction, and divided into three integrally-formed compart ments, 1) Z) b", by diaphragms c c c".

In the diaphragm or partition wall 0 is formed a valve-seat, d, having a valve, d, working therein, attached to a stem, 0?, and secured to the end of a lever, e, for operating the same.

Communicating with and rigidly attached by screw-threads to the partition of the chamber b is a large nozzle, f, and small steamjet pipe, f. Above this nozzle f and jetpipe f, and at right angles thereto, is placed a similar nozzle, 9, and jetpipe 9, attached to the walls 0 c of the chamber 1)", which chamber 7) is in communication with a supply-pipe, h, while the chamber Z) below is pro vided with an exit-pipe, h.

At the top of the shell a is placed a steampipe, h, communicating with a port, 2', formed in the side of the shell a, in which, and communicating with the chamber 1) by means of the nozzle f, is a valve, i, operated by the lever 6. This lever e is fulcrumed between the valves t" and d in such a manner that when one of the valves, (1, is closed the other, i, is open.

The lifting tubes or nozzles g may be readily detached through the opening h used for the admission of steam, while the forcingtubes ff in the chamber 1) below may in the same manner be detached through the opening if of the exit-pipe.

(Model.)

The operation of my improved device is as follows: To start the injector, the valve t" is closed and the valve d is opened by depressing the lever e, and steam, being admitted through the opening h passes through the nozzles g g, producing a vacuum or partial vacuum in the chamber 1)", and raising the water through the pipe h and chamber 1), and discharging it from the head 9 into the chamber b,whence it passesthrough the valve (1 to the waste or leakage pipe 70. \V hen the current is fully established, the lever e is raised, which closes the valve (1 and opens the valve i. The steam then passes from the port 6 through the valve and nozzle f, as well as through the nozzle 9, and, acting upon the water in the head 9, induces a current from the chamber 1), and drives it through the head f, chamber 1), and discharge-pipe it into the boiler.

The construction and operation just described have the advantage of the liftingtubes 9 g and forcing-tubes f f at right angles to each other, which is considered a better position than if parallel to each other, being operated in a more easy and simple manner.

Each tube and nozzle may be detached and replaced without disturbing the other.

Fig. 3 shows a construction similar to Figs. 1 and 2, the internal parts being the same, while the outside arrangements differ in having globe-valves with separate means for operating the same, the said valves being articles of general merchandise, and procured at any machine-shop,

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. In an injector, the combination, with a shell, as to, having integrally-formed compartments, as b b b", and a steam-port, as t, of removable vertical lifting-tubes, as g g, a supply-pipe, as h, a steaminlet valve, as 1', horizontal forcing-tubes, as f f, a waste-water discharge-valve, as d, and mechanism, substantially as described, for operating the valves, as and for the purpose set forth.

2. In an injector, the combination, with a shell having an integrally-formed steam-port and a waste-water chamber, each provided I my hand this 9th day of September, A. D. with a valve-seat, of valves, as 7" and d, con- 1885.

nected with an actuating-lever fulcrumed between said Valves, so that when one valve is WILLIAM SHERRIFF' 5 open the other will be closed, substantially as Witnesses:

described, and for the purpose stated. W. O. BARR,

In testimony whereof I have hereunto set M. E. HARRISON.
